Microwave dielectric material with near-zero temperature coefficient of resonance frequency and preparation method thereof
The invention discloses a microwave dielectric material with a near-zero temperature coefficient of resonance frequency. Mg<2>TiO<4> and Li<2>TiO<3> are compounded according to a mass ratio of (1-x)Li<2>TiO<3-x>Mg<2>TiO<4> to finally form a three-phase composite system of Mg<2>TiO<4>, Li<2>MgTi<3>O<8> and Li<2>TiO<3>, the mass percent x of Mg<2>TiO<4> is more than 0 and less than 100%. According to the invention, Mg<2>TiO<4> and Li<2>TiO<3> are compounded, so that on one hand, the poor sintering performance of Mg<2>TiO<4> is improved, and the Mg<2>TiO<4> can be sintered and molded; and on the other hand, [tau]f compensation is carried out through Li<2>TiO<3> with a positive [tau]f value, so that the whole system has a near-zero [tau]f value, and the sintering temperature of the system can also be improved due to the relatively low sintering temperature of Li<2>TiO<3>.
本发明公开了一种谐振频率温度系数近零的微波介电材料，由Mg2TiO4和Li2TiO3按照(1‑x)Li2TiO3‑xMg2TiO4质量比复合，最终形成Mg2TiO4、Li2MgTi3O8和Li2TiO3三相复合体系，其中，所述Mg2TiO4的质量百分数x为：0＜x＜100％；本发明通过将Mg2TiO4与Li2TiO3进行复合，一方面改善了Mg2TiO4较差的烧结性能，使其能够烧结成型；另一方面通过具有正τf值的Li2TiO3进行τf补偿，使整个体系具有近零的τf值，且Li2TiO3较低的烧结温度也能改善体系的烧结温度。
